SULKY.

SPECIFICATION forming part of Letters Patent No. 395,375, dated January 1, 1889.

Applail filed October 17, 1888. Serial No. 288,393 (No model.)

T0 all whom t may concern:

Be it known that l, CHARLES O. YALE, of Rome, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Sulkies; and I do hereby declare that the following is a full, clear, and exact description of the invention,

I which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

My invention relates to a wagon or twowheeled sulky; and it consists in the mechanism hereinafter pointed out and claimed, the object of my invention being to relieve the friction and strain due to drivin ga sulky on a short curve.

in the drawings, Figure il shows a rear view of a sulky of my construction. Fig. represents a vertical central section of Fig. 1 on line X X, the broken lines indicating a portion of the rim of the wheel removed; and Fig. 3 represents a side view of the adjusting mechanism, taken on line Y Y, Fig. 1, the broken lines indicating; a portion of the wheel removed. Fig. i 'represents the underside of `the seat, showing the slots tor adjusting the seat; and Fig. 5 represents a cross-section on line s s, Fig. fi, representing the bolt-heads and bolts inthe slots.

ln the lrawvings,1 l represent the wheels, of ordina-ry colistrnction, which are mounted on jointed axle-tree L), provided with joints 3 5l j ust inside of the hubs, that portion of the axle-tree which tits in the llubsbeing pivoted to axle 1, so as to form a joint or hinge. The portion of the axle-tree which tits in the hub, forming the l earing on which the wheels are mounted, is provided wit-l1 crank-anus t 4, provided with perfor-ations 5, Figs. 2 and 3. The crank-arms i -t are connected with brace tions 5 in the crank-arms, as shown in Figs. 2

and 3, by means of which the seat may be 5o raised or lowered. The brace is pivoted at opposite ends to plates '7 7 at 10, the joints of t-he brace-arms with the plate falling below joints f3 3 in the axle-tree. a represents the shafts. The purpose of this construction is to relieve the axle-tree and wheels from undue frictionwhen the sulky is driven on a short curve and enables the location of the drivers seat to be shifted to the inner side of the center of the curve.

Another feature of my invention consists in having seat 1 1 ad j ustably mounted on extension-arms 12 and adjustable forward or backward by slots 13, Fig. e, which is accomplished by means of nuts le, which pass through slots 13 in the seat loosely, so as to allow the seat to be moved by the driver liiackward or forward, as he may desire.

That I claim as new, and desire to secure by Letters Patent, is-

1. The combination, in a snlky, of an axletree jointed inside of the hubs, the outer jointed portions of the axle-tree having downwardly-proj ccting angles, and a brace iiexibly connected to the downwardly-projecting angles, substantially as set forth.

2. The combination, in a sulky, of the jointed axle-tree, the outer jointed portions of the axle-tree provided with downwardly-projecting angles, and a vertically-adjustable brace pi voted to the downwardly-projectin g angles, substantially as set forth.

il. The combination, in a sulky, of the jointed axle-tree, the outer jointed portion of the axle-tree provided with downwa17d-projecting (5 by adjustable plates 7, provided with bolti holes, the crank-arms and plates being held angles, a brace pivoted to the downwardlyprojecting angles, and the horizontally-adjustable seat mounted on the brace, substantially as set forth.

In witness whereof l have affixed my signature in presence of two witnesses.

CHARLES O. YALE.
